The specific embodiment
Below in conjunction with description of drawings the invention process form.In each figure, identical or considerable part is represented with prosign, the simple sometimes and even omission of its explanation.
Example 1
Fig. 1 is the horizontal direction cutaway view of three frame munnions of floor gangway, building of the present invention.The floor doorway device of the elevator of seeing from floor gangway one side of elevator and shown in Figure 7 same is so quote Fig. 7.In Fig. 7, the 1st, the floor gangway door of elevator, the 2nd, about relatively and three frame munnions of configuration, 3 is three frame upper ledges.In Fig. 1, the 2nd, three frame munnions representing with the section of horizontal direction, the 4th, panel, 4a is the gangway side panel, 4b is cage side panel (to call panel 4a, 4b in the following text), and the panel 4 that constitutes the appearance of three frame munnions is divided into floor side panel 4a and cage side panel 4b at the depth direction of three frame munnions 2.The 12nd, orbital groove, the cutting part side end that adjoins each other of panel 4a, 4b constitute orbital groove 12 after the private side of three frame munnions 2 bends to the L font.The other end of panel 4a, 4b respectively overleaf inside bend become the コ font.The 11st, strobe track is used for connection and reinforced panel 4a, 4b, as shown in Figure 1, is installed in the inner face of panel 4a, 4b.The 10th, the fire prevention gate is fallen from three frame munnion upper ledge 3 (see figure 7)s by orbital groove 12 guiding.The 5th, reinforcement (connecting panel) is erected at the inner face of panel 4a, each end of 4b rear side, and its end combines with the end of panel 4a, 4b respectively.In addition, the purpose of reinforcement 5 is the rigidity that are used to keep panel 4a, 4b, usually the short transverse of panel 4a, 4b separate fixed interval, several piece for example is divided into 3 places installs.
Fig. 2 is three lateral plans that the frame munnion is seen from the rear side of appearance of this example 1.In 2 figure, the 7th, slotted hole, the 8th, rivet.Panel 4a, 4b respectively and the joint portion of 5 of reinforcements have the slotted hole 7 that along continuous straight runs extends, combine with reinforcement 5 by rivet 8, when het expansion, panel 4a, 4b can slide at the joint portion along continuous straight runs.
Fig. 3 is the horizontal direction cutaway view of the heat expands state of three frame munnions of expression, the state of three frame munnions of (A) expression tradition warpage when het expansion, (B) the repressed state of the expression the present invention's warpage of three frame munnions when het expansion.In traditional example, because panel 4a, 4b and reinforcement 5 are to fix at welding fixed part 5a, so panel 4a, 4b are subjected to the constraint of reinforcement 5, shown in Fig. 3 (A), warpage takes place in panel 4a, 4b.And adopt this example 1, when fire took place, behind panel 4a, 4b het expansion, because rivet 8 slides, the constraint that panel 4a, 4b and reinforcement 5 are subjected in the horizontal direction relaxed, so shown in Fig. 3 (B), can make whole even expansion of panel 4a, 4b.Thereby can prevent to open by the expansion of orbital groove 12 and cause fire prevention the coming off of gate 10, improve fire resistance.Again because the constraint of counter plate 4a, 4b relaxes, and the distortion that strain produces is controlled, so can reduce the operation of outer replacing appearance part when behind fire, restoring panel.
Have, the present invention can slide at the joint portion along continuous straight runs with panel 4a, 4b because of reinforcement 5 again, so when three frame munnions were made, the panel strain that the operating error in the time of also can welding by control causes improved aesthetic appearance.
Fig. 4 is the horizontal direction cutaway view after appending liner plate on the structure of three frame munnions of the present invention.Liner plate is located at the rear side of three frame munnions, is the member in order to separate with the lifting borehole wall.In more detail, in order to prevent fires, usually will be at lifting borehole wall shop mortar, on the other hand, also have in the inside of three frame munnions and to irritate mortar, and the floor doorway device of the elevator that has saves the mortar of three frame munnions for cost-cutting.At this moment, be exactly liner plate for the mortar of lifting borehole wall side and three frame munnions are separated the member that uses.In Fig. 4, the 6th, liner plate, as shown in Figure 4, liner plate 6 section in the horizontal direction is to engage with the outside of reinforcement 5, in vertical direction, forms (diagram is slightly) equal length usually with three frame munnions 2.In the past, liner plate was general the same with reinforcement, waited by welding and was fixed in panel, and therefore, when fire took place, also the same with the reinforcement panel that retrains of liner plate became one of reason of panel generation warpage.For this reason, as this example 1, by liner plate 6 and panel 4a, 4b are installed on the reinforcement 5 separatedly, like this, both liner plate 6 can be set, and can not make again by relaxing panel 4a, 4b and reinforcement 5 constraint in the horizontal direction and prevent that the effect of the appearance warpage of panel 4a, 4b is affected.Owing to can under the prerequisite that can not encourage panel 4a, 4b warpage, liner plate 6 be set, so the input amount of mortar is selected in the requirement can be according to elevator setting the time, thus can cost-cutting.
More than explanation is three frame one examples with fire prevention gate, and the present invention promptly be used in shown in Figure 8 do not have the fire prevention gate, be not establish on the panel on three frames of orbital groove, also have same effect.
Example 2
Below, example 2 of the present invention is described.Fig. 5 is three lateral plans that the frame munnion is seen from the rear side of appearance of this example 2.In Fig. 5, reinforcement 5 is erected at each end inner face of the rear side of panel 4a, 4b, its end respectively with the welding of the end of panel 4a, 4b, perhaps fix with the combination of rivet and lining cement etc.
Below, the example of appending liner plate 6 in example 2 is illustrated.
When the reinforcement 5 of this example 2 is made of the big material of linear expansion factor of the material of linear expansion factor ratio panels 4a, 4b, also can as 4 figure, the outside of liner plate 6 with reinforcement 5 be engaged.At this moment, liner plate 6 is to separate and engage with reinforcement 5 with panel 4a, 4b, and the linear expansion factor of liner plate 6 is more than linear expansion factor equal of reinforcement 5, therefore and example 1 same, both liner plate 6 can be set, and can not make again by relaxing panel 4a, 4b and reinforcement 5 constraint in the horizontal direction and prevent that the effect of the appearance warpage of panel 4a, 4b is affected.Owing to can under the prerequisite that can not encourage panel 4a, 4b warpage, liner plate 6 be set, so the input amount of mortar is selected in the requirement can be according to elevator setting the time, thus can cost-cutting.
More than explanation is three frame one examples with fire prevention gate, and the present invention promptly be used in shown in Figure 8 do not have the fire prevention gate, be not establish on the panel on three frames of orbital groove, also have same effect.
Example 3
Below, example 3 of the present invention is described.Fig. 6 is three lateral plans that the frame munnion is seen from the rear side of appearance of this example 3.In Fig. 6, reinforcement 5 is erected at each end inner face of the rear side of panel 4a, 4b, and the end of reinforcement 5 combine with the both ends of panel 4a, 4b respectively with the different position of height in the horizontal direction and also can rotate.In addition, strobe track 11 Fig. 1 as described above is such, is installed in the inner face of panel 4a, 4b.More particularly, the end of the floor side of strobe track 11 (panel 4a side) is waited by welding and is completely fixed, and the slotted hole that extends is along the vertical direction then established in the end of cage side (panel 4b side), the inboard of panel 4b welding thru-bolt (diagram slightly).That is to say that panel 4b is mounted to relatively strobe track 11 and above-below direction slides.
Like this, when fire takes place, when panel 4a, 4b het expansion, because panel 4a, 4b het expansion in the horizontal direction, at panel 4a, 4b separately and the joint portion of 5 of reinforcements, the direction application of stress of opening mutually to horizontal direction.In addition, the both ends of reinforcement 5 are respectively in the combination rotationally of 1 place, so panel 4a, 4b can do the above-below direction slip mutually.The result, because the both ends of reinforcement 5 combine with panel 4a, 4b with the different position of height in the horizontal direction, so can on reinforcement 5, produce moment, connect its both ends and panel 4a, 4b between the alignment of combined hole rotate near the direction (i.e. 2 directions that panel 4a, 4b leave) of level.Counter plate 4a, 4b relax to the constraint of horizontal direction when making het expansion thus, can suppress warpage, therefore can prevent to be opened by the expansion of orbital groove 12 to cause coming off of fire prevention gate 10, improve fire resistance.Because the constraint of counter plate 4a, 4b relaxes, the distortion that strain produces is controlled, so take place can reduce the operation of changing the appearance part when panel is restored in the back at fire.
More than explanation is three frame one examples with fire prevention gate, and the present invention promptly be used in shown in Figure 8 do not have the fire prevention gate, be not establish on the panel on three frames of orbital groove, also have same effect.
The invention of above example 1～3 all can obtain the effect of the object of the invention by the independent enforcement of above-mentioned each example, and implement as if the invention shown in these each examples is made up, and then effect is better.
The present invention is because of having the formation of above explanation, so in the floor doorway device of elevator with fire prevention gate, even three frame munnion generation het expansions when fire, because the constraint in the horizontal direction of panel and reinforcement relaxes, so can the control panel warpage, prevent to open and cause fire prevention the coming off of gate, improve fire resistance by the expansion of orbital groove.In addition, even do not have the floor doorway device of the elevator of fire prevention gate, when restoring panel behind fire, because the constraint of counter plate relaxes, the distortion that strain produces is controlled, so can reduce the operation of changing the appearance part.In addition, when three frame munnions are made, because of the strain of the panel that operating error took place, improve aesthetic property in appearance in the time of can welding by control.In addition, can under the prerequisite that can not encourage the panel warpage, liner plate be set, so the input amount of mortar is selected in the requirement can be according to elevator setting the time, with cost-cutting.
